DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through8 thereof, a new grain storage assembly embodying the principles andconcepts of an embodiment of the disclosure and generally designated bythe reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 8, the granular material storagecapacity increasing device 10 and system generally comprises a housing12 including a first side wall 16 and a second side wall 18. Each of thefirst 16 and second 18 side walls engages and extends upwardly from aground surface and each of the first and second side walls is verticallyoriented and has an upper edge 20. A roof structure 22 is attached toand extends between the first 16 and second 18 side walls. The roofstructure 22 engages the upper edges 20 of the first 16 and second 18side walls. More particularly, the roof structure 22 includes aplurality of roof trusses 24 wherein each of the roof trusses 24includes an inner chord 26. The roof trusses 24 are spaced from eachother. It should be understood that the housing 12 will further includea pair of end walls, not shown, extending between the first 16 andsecond 18 side walls to form a base wall having a generally rectangularconfiguration. The roof structure 22 includes inner 26 and outer chords28 attached together by supports 30 and the trusses 24 may moreparticularly define hoop trusses. The housing 12 is of conventionalnature and a similar structure is disclosed by U.S. Pat. No. 7,814,714,incorporated herein by reference.

A plurality of panels 32 is attached to the roof structure 22 to definean auxiliary storage capacity above the first 16 and second 18 sidewalls supported by the roof structure 22. Each of the panels 32 extendsbetween and is attached to adjacently positioned ones of the innerchords 26 as shown in FIG. 3. The panels 32 may be attached to the innerchords 26 with conventional securing means including bolts, fasteners,brackets and the like extending trough the panels 32 and engaged withthe inner chords 26. The panels 32 each are horizontally oriented andoverlap each other to form a continuous inner wall extending upwardlyalong the inner chords 26 to a predetermined height. The panels 32 areattached to the roof structure 22 to define an auxiliary storagecapacity above the first 16 and second 18 side walls and which issupported by the roof structure 22. As is well known in the art,granular material 14, when stored, is often limited to the angle ofrepose of the granular material 14. This angle is dictated by thecoefficient of fiction between the particles of the granular materialbeing stored. The granular material 14 may include grain, road salt,sand and the like and each has an angle of repose which limits theheight to which it may be piled. Moreover, there are classificationswithin each category that again must be taken into consideration. Thus,within grain it is known that barley has an angle of repose of 30° whilethat of wheat is 28°. When filling a conventional storage housing thegranular material 14 cannot be piled so high as to rise above the basewall comprising the first 16 and second 18 side wall of the housing 12because the material 14 would push against an outer covering, not shown,positioned on the outer chords 32. The height limit of the pile must bemonitored to ensure that the height and the angle of repose do notcombine to spill material over the base wall. The panels 32 are added tothe housing 12 to allow the height of the pile to be increased above thebase wall which, in turn, increases the overall granular materialstorage capacity of the housing 12. However, once the pile approaches anapex of the housing 12, filling must stop. For this reason, the panelsneed not be attached to the inner chords to the apex but may bediscontinued at the predetermined height which is equal to the limit oflateral filling of the housing 12 when the material 14 pile is at such aheight that no more material 14 may be added to the housing 12.

Each of the panels 32 is elongated and has a first end 34, a second end36, an upper edge 40, a lower edge 38, an inner surface 42 and an outersurface 44. Generally, the inner surface 42 will be the surface facinginward of the housing 12 while the outer surface 44 will face the innerchords 26. The terms “upper” and “lower” are being used for clarity onlyas the panels 32 may be oriented as needed with respect to the housing12. An upper bend 48 is positioned adjacent to the upper edge 40 and anupper flange 49 is defined between the upper bend 48 and the upper edge40. A lower bend 46 is positioned adjacent to the lower edge 38 and alower flange 47 is defined between the lower bend 46 and the lower edge38. A primary bend 50 is positioned between the upper 48 and lower 46bends. The upper 48 and lower 46 bends each form a flange angle 52, 51,respectively, less than 180° in the inner surface 42 while the primarybend 50 forms a primary angle 53 greater than 180° and less than 270° inthe inner surface 42. As such, an obtuse angle is formed in the outersurface 44 at the primary bend 50. More particularly, in the embodimentof FIG. 1, the flange angle 51 of the lower bend 46 is between 115° and135°, and may more particularly be between 120° and 130°. The flangeangle 52 of the upper bend 48 is between 145° and 170° and may moreparticularly be between 152° and 162°. The primary angle 53 may bebetween 235° and 270° and more particularly between 250° and 267°.

The outer surface 44 of the upper flange 49 is contoured to match theinner surface 42 of the lower flange 47 and the outer surface 44 of thelower flange 47 is contoured to match the inner surface 42 of the upperflange 49. In this manner, the upper 49 and lower 47 flanges of adjacentpanels 32 may be overlapped and nested with each other. As shown in FIG.8, which will be discussed below, this may be particularly useful wherethe upper 49 and lower 47 flanges are rounded and will help account fornon-linear inner chord 26 structures which are conventionally arcuate.

In general, a plane is defined extending through and is coextensive withthe upper 48 and lower 46 bends. A distance between the primary bend 50and the plane is greater than a distance between the plane and the lower38 and upper 40 ends. This places the primary bend 50 further away fromthe inner chord 26 than the lower 38 and upper 40 ends when the panel 32is mounted on the inner chord 26. The panel 32 of FIG. 1 includes afirst length measured from the upper bend 48 to the primary bend 50 thatis greater than a second length measured from the lower bend 46 to theprimary bend 50. The first length defines a first leg 71 of the panel 32and the second length defines a second leg 72 of the panel. Moreparticularly, the first length may be at least 1.4 times the secondlength. This structure resists bending, warping or crushing of the panel32 when the panel 32 is subjected to gravitational forces from material14 piled within the housing 12. The first length may generally bebetween 7.0 inches and 10.0 inches, while the second length maygenerally be between 3.0 inches and 6.0 inches. Each of the upper 49 andlower 47 flanges may have a length between 0.50 inches and 4.0 inchesand more particularly between 0.75 inches and 1.50 inches. Each of theupper 49 and lower 47 flanges has a plurality of apertures 54 extendingtherethrough for receiving the securing means for coupling the panels 32to the inner cord 26. The apertures 54 of one panel 32 are alignablewith the apertures 54 of the other panels 32 to also allow coupling ofthe panels 32 together along the upper 49 and lower 47 flanges toprevent material 14 from passing between abutting panels 32. The panels32 may each have a width substantial enough to attach the panels 32 toadjacent ones of the trusses 24 though it should be understood that thepanels 32 may have a width to allow each panel to be attached to andextend between more than two of the trusses 24.

FIGS. 1-5 and 7 depict variations of the panel including planar sectionswhile FIGS. 6 and 8 include some rounded features. More particularly,FIG. 7 includes flanges 56 having bends 57 therein resulting in endsangled upwardly from the upper 48 and lower 46 bends to assist innesting of the flanges 56. This version further includes a pair ofprimary bends 58 which are spaced from each other to form a trapezoidalong the primary bends 58, the lower bend 46, the upper bend 48 and aline extending between the upper 48 and lower 46 bends. The trapezoidmay be an isosceles trapezoid. FIGS. 6 and 8 include rounded flanges 60,62 to aid in the nesting of the panels 32 when mounted along an arcuatesurface. FIG. 6 retains a triangular shape between the flanges 60 whileFIG. 8 includes a rounded shape between the flanges 62. The roundedflanges 60, 62 of FIG. 8 may be formed on radii between 0.40 inches and0.80 inches while a central portion of that panel between the roundedflanges may be formed on a radius between 4.0 inches and 8.0 inches

In use, the panels 32 are placed on the inner chords 26 of the housing12 as shown to form an extended interior wall extending upwardly fromthe first 16 and second 18 side walls. The panels 32 are shaped toresist being deformed when material 14 placed in the housing 12 beginsto exert force on the panels 32. With the version shown in FIGS. 1-5,the upper edge 40 of each panel 32 is placed on the inner chords 26vertically above a corresponding lower edge 38. This orients the firstleg 71 of a triangle, between the upper bend 48 and the primary bend 50,facing downwardly into the housing 12 to direct the force of thematerial 14 generally lateral, or horizontal, with respect to thetrusses 24 to counter the angle of repose of the granular material 14.Specifically, the primary angle 53 may be selected such that the firstleg 71 forms an angle with respect to a horizontal plane approximatelyequal to 90° minus the angle of repose. For instance, if the angle ofrepose is 23°, the panel 32 may be shaped such that the inner surface 42of the first leg 71 forms a 67° angle with a horizontal plane when thelower 47 and upper 49 flanges are attached to the inner chord 26. Suchan angle will cause the gravitational and frictional forces of thematerial 14 to be displaced laterally. Because one objective is tolaterally displace the forces of the material 14, it should beunderstood that the primary angle 53 may be altered depending on theangle of the inner chord 26. Thus, panels of various angles may be usedtogether as the angle of the inner chord 26 varies. Alternatively, thepanels 32 may be provided each having an identical shape but with aprimary angle 53 chosen such that an overall composite effect of lateraldisplacement is obtained. This direction of the gravitational andfrictional forces of the material 14 will inhibit deformation of thepanels 32 and prevent upward pressure on the trusses 24. The panels 32allow the material 14 to be piled above the first 16 and second 18 sidewalls and thereby increase the capacity of the housing 12.

With respect to the above description then, it is to be realized thatthe optimum dimensional relationships for the parts of an embodimentenabled by the disclosure, to include variations in size, materials,shape, form, function and manner of operation, assembly and use, aredeemed readily apparent and obvious to one skilled in the art, and allequivalent relationships to those illustrated in the drawings anddescribed in the specification are intended to be encompassed by anembodiment of the disclosure.

Therefore, the foregoing is considered as illustrative only of theprinciples of the disclosure. Further, since numerous modifications andchanges will readily occur to those skilled in the art, it is notdesired to limit the disclosure to the exact construction and operationshown and described, and accordingly, all suitable modifications andequivalents may be resorted to, falling within the scope of thedisclosure.
